1

A team uses Azure Pipelines to build a .NET Core application. The build pipeline runs successfully, but the release pipeline fails when deploying to Azure App Service with the error: 'ERROR_FILE_IN_USE'. What is the most likely cause?

2

A development team is designing a build pipeline for a microservices application. They want to ensure that each service is built and tested independently, but they also need to run integration tests that span multiple services. What is the recommended approach?

3

A company uses Azure Pipelines with YAML-based pipelines stored in a Git repository. The pipeline triggers on every push to the main branch, but the team wants to reduce unnecessary builds when only documentation files are changed. What is the best way to achieve this?

4

A team is implementing a release pipeline for a Node.js application. They want to run integration tests against a temporary environment that is destroyed after the tests complete. Which strategy should they use?

5

Which TWO actions should be taken to secure secrets in Azure Pipelines? (Choose two.)

6

You are reviewing an Azure Policy definition applied to an Azure DevOps project. The project has a build pipeline that deploys to production. What is the effect of this policy on the build pipeline?

7

Your company has a large monorepo with multiple microservices. You have a single YAML-based Azure Pipeline that builds the entire solution on every commit to the main branch. The pipeline takes over an hour to complete, causing long feedback loops. Developers often submit changes to only one service, but the whole pipeline runs. You need to reduce build time while maintaining quality. You are considering splitting the pipeline into multiple pipelines, each for a service, and using path triggers. However, some services have dependencies on shared libraries that are updated infrequently. You also need to ensure that integration tests that span multiple services still run when necessary. What should you do?

8

A development team is configuring a YAML-based pipeline in Azure Pipelines. The pipeline must meet the following requirements: - Build only the main branch. - Run integration tests after a successful build. - Deploy to a staging environment only if tests pass. - Handle failures gracefully by sending a notification to the team. You need to define the pipeline structure. Which TWO configurations should you include?

9

Refer to the exhibit. The pipeline is configured as shown. A developer pushes a change to the `main` branch that modifies a file under `src/Controllers/HomeController.cs` and also adds a new file under `docs/readme.md`. Which of the following best describes what happens?

10

Your organization uses Azure Pipelines for CI/CD. The current pipeline for a .NET Core application builds and runs unit tests, then deploys to a staging environment. The team wants to add a step to run integration tests against the staging environment after deployment, and only if integration tests pass, promote the build to production. The integration tests require a database connection string that is stored as a secret in Azure Key Vault. The pipeline uses a service principal with permissions to read secrets from the Key Vault. You need to modify the pipeline to meet these requirements while ensuring security best practices. Which action should you take?

11

You have a multi-stage YAML pipeline that deploys to Azure Kubernetes Service (AKS). The pipeline uses a deployment job with a strategy of 'runOnce'. You need to ensure that if the deployment fails, the pipeline automatically redeploys the previous successful version. Which strategy should you use instead?

12

You are designing a build pipeline that produces a NuGet package. The pipeline must conditionally sign the assembly only when the build is triggered by a tag starting with 'v' (e.g., v1.0.0). The pipeline uses a script task that signs the assembly. Which expression should you use in the condition of the script task?

13

You need to ensure that the pipeline waits for manual approval before deploying to the production environment. The production environment is named 'Production'. Which configuration should you add to the deployment job?

14

You are designing a release pipeline that uses Azure App Service deployment slots. The pipeline must perform a swap after deployment to the staging slot. Which three tasks or actions should you include in the pipeline? (Select all that apply.)

15

You are creating a YAML pipeline that builds a .NET Core application. The pipeline must use a multi-stage build with separate stages for 'Build', 'Test', and 'Deploy'. The 'Deploy' stage should only run if both 'Build' and 'Test' succeed. Which two conditions can you use to achieve this? (Select all that apply.)

16

You are designing a build pipeline that uses a combination of tasks. The pipeline must compile code, run unit tests, and then publish code coverage results. Match each task with its appropriate placement in the pipeline order. The tasks are: 'Visual Studio Test', 'Publish Code Coverage Results', 'Visual Studio Build'. The correct order is: 1. Build, 2. Test, 3. Publish coverage.

17

You have a YAML pipeline that builds a .NET application. You need to ensure that the pipeline uses the .NET SDK version 6.0.x. Which task should you add to the pipeline?

18

You have a release pipeline that deploys to multiple stages. You want to ensure that a manual approval is required before deploying to the production stage. Which approach should you use?
